The 0.156\" (3.96mm) pitch is the standard spacing for this family, giving enough room for the IDC slot to bite cleanly through the insulation without crowding adjacent wires. A closed end stops the cable from pushing through the housing, and the polarizing key ensures the mating header can only be inserted one way — both features that save rework on a harness build. Tin contacts with 80.0µin (2.03µm) of plating handle the moderate mating-cycle duty of an internal harness — no gold needed for this application. ## Wire Gauge Fit — 20 AWG Only This receptacle is spec'd for 20 AWG wire only.","metaTitle":"TE MTA-156 3-643818-5, 5-Position IDC Receptacle, 20 AWG","metaDescription":"TE Connectivity MTA-156 3-643818-5 receptacle, 5 positions, 0.156\" pitch, IDC termination for 20 AWG discrete or ribbon cable.
